Ingredients

• 1 28-ounce can whole peeled tomatoes
• 8 garlic cloves, peeled, crushed
• 2 anchovy fillets packed in oil
• 1/4 cup (1/2 stick) unsalted butter, cut into small pieces
• 1/2 teaspoon crushed red pepper flakes plus more for serving
• Kosher salt, freshly ground pepper
• 12 ounces bucatini or spaghetti
• Finely grated Parmesan (for serving)

Instructions

1. Preheat oven to 425°F. Combine tomatoes (crushing them with your hands), garlic, anchovies, butter, and 1/2 teaspoon red pepper flakes in a 13x9" baking dish; season with salt and black pepper. Roast, tossing halfway through, until garlic is very soft and mixture is jammy, 35–40 minutes. Using a potato masher or fork, mash to break up garlic and tomatoes.
2. Meanwhile, cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain, reserving 1/2 cup pasta cooking liquid.
3. Return pasta to pot and add tomato sauce and pasta cooking liquid. Cook over medium-high heat, tossing until sauce coats pasta, about 3 minutes. Serve topped with Parmesan and more red pepper flakes.
4. DO AHEAD: Tomato sauce can be made 4 days ahead. Let cool; cover and chill. Reheat before mixing with pasta.
